Monitoring changes in precipitation and radiative energy using satellite data and climate models

摘要: Current changes in the tropical hydrological cycle, including water vapour and precipitation, are presented over period 1979-2008 based on a diverse suite of observational datasets and atmosphere-only climate models. Models capture observed variability moisture while reanalyses cannot. Observed precipitation is highly dependent upon satellite instruments employed only cursory agreement with model simulations, primarily relating to the interannual associated El Nino Southern Oscillation. All display positive relationship between surface temperature but large spread. The tendency for wet, ascending regions become wetter at expense dry, descending regimes general reproduced. Finally, frequency extreme shown rise warming the observations for ensemble mean spread simulations. The influence Earth’s radiative energy balance relation cycle are discussed
